Anthurium plant named ‘ANTHEUYK’

ABSTRACT

A new Anthurium plant named ‘ANTHEUYK’ particularly distinguished by having shiny, weakly blistered, pink, orbicular-cordate and very durable spathes that retain the original color for a very long period of time, dark green and ovate-cordate, durable leaves, pink spadices with orange-yellow tips, early and rich flowering continuously throughout the year, and a plant height of 23.0 cm to 27.0 cm is disclosed.

Genus and species: Anthurium andraeanum L.

Variety denomination: ‘ANTHEUYK’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium,botanically known as Anthurium andraeanum L., and hereinafter referredto by the variety name ‘ANTHEUYK’. The new Anthurium plant is a productof a planned breeding program conducted by the inventor in Bleiswijk,the Netherlands. The objective of this breeding program was to create anew 23.0 cm to 27.0 cm height plant with shiny and weakly blistered,pink, orbicular-cordate and very durable spathes.

The new variety originated from a cross-pollination made in September2008 in Bleiswijk, The Netherlands. The female parent was a pinkAnthurium pot plant designated ‘11376-07’ (unpatented), and the maleparent was a pink Anthurium pot plant designated ‘ANTHDATAM’ (U.S. PlantPat. No. 27,699).

A single plant was selected from the progeny of the stated cross inSeptember 2010 and has been asexually reproduced repeatedly by tissueculture in Bleiswijk, The Netherlands, over a 6-year period. The presentinvention has been found to retain its distinctive characteristicsthrough successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in theEuropean Union on Nov. 25, 2016. ‘ANTHEUYK’ has not been made publiclyavailable or sold anywhere in the world more than one year prior to theeffective filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Bleiswijk, The Netherlands:

-   -   1) Shiny and weakly blistered, pink, orbicular-cordate spathes;    -   2) Pink spadices with orange-yellow tips; and    -   3) Green, ovate-cordate leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographswhich show the overall plant habit including blooms, bud and foliage ofthe plant; the colors shown are as true as can be reasonably obtained byconventional photographic procedures. The photographs are of a 28-weekold plant grown in a greenhouse in Bleiswijk, The Netherlands, inSeptember 2018. Colors in the photographs may differ from the colorvalues cited in the detailed botanical description, which accuratelydescribe the actual colors of the new variety.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘ANTHEUYK’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 28-week oldplants which were planted from tissue culture in 9 centimeter (diameter)pots and grown in a glass greenhouse between 19° C. and 24° C.Observations were made in September 2018. Color readings were takenunder 5000 lux natural light in the greenhouse. Color references areprimarily to The R.H.S. Colour Chart of The Royal Horticultural Societyof London (R.H.S.) (2015).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

The female parent plant of ‘ANTHEUYK’, cultivar ‘11376-07’, is no longerin existence, so a meaningful comparison cannot be made.

‘ANTHEUYK’ differs from the male parent plant ‘ANTHDATAM’ (U.S. PlantPat. No. 27,699) in that ‘ANTHEUYK’ has acute leaf apexes and spatheswith an upper surface color of RHS 38A, whereas ‘ANTHDATAM’ hasacuminate leaf apexes and spathes with an upper surface color of RHS52A.

‘ANTHEUYK’ differs from similar commercial variety ‘ANTHDINWAQ’ (U.S.Plant Pat. No. 26,048) in that ‘ANTHEUYK’ has acute leaf apexes andspathes with an upper surface color of RHS 38A, whereas ‘ANTHDINWAQ’ hasacuminate leaf apexes and spathes with an upper surface color of RHS51A. Additionally, ‘ANTHEUYK’ has a longer plant height than‘ANTHDINWAQ’.

‘ANTHEUYK’ differs from similar commercial variety ‘ANTHEOCMA’(unpatented) in that ‘ANTHEUYK’ has ovate-cordate leaves andorbicular-cordate spathes with an upper surface color of RHS 38A,whereas ‘ANTHEOCMA’ has elliptical-cordate leaves and ovate spathes withan upper surface color of RHS 38D.

I claim:
 1. A new and distinct variety of Anthurium plant named‘ANTHEUYK’, substantially as illustrated and described herein.
